SPECIFICATION forming part of Letters Patent N o. 687,242, dated November 26, 1901. Application filed January 28, 1901. Serial No. 45.183. (No model.)

To ctZZ whom, t may concern.-

Be it known that IgEDMUND KIKU'r, a subject of the King of Prussia, German Emperor, and a resident No. 6 Stuttgarter Platz, Charlottenburg, near Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Means for Utilizing the Working Power of Compressed Inammable Gas, of which the following is a specification.

This invention relates to means for utilizing the working power of compressed infiammable gas or gases; and my invention consists in general in. utilizing the compressed inflammable gas or gas mixture ina jet-blowing apparatus or in the jet-nozzle proper ofvv the same, and in particular in employing the jet-blowing apparatus or the jet-nozzle proper, in which the compressed inflammable gas is made use of for driving a turbine engine by either the mixture'of thc combustiongases and air produced by the jet-blowing apparatus or solely by the air sucked in by said apparatus and driven through the same by the action of the jet ofthe compressed inflammable gas. Owing to this means the turbine engine, or, more particularly, the turbine wheel of said engine, is subjected either but to a comparatively low temperature or heat or to no heat at all, which is the case if the turbine wheel is actuated by the air sucked in by the jet-blowing apparatus.

In order to make myinvention more clear, Irefer to the accompanying drawing, in which is represented a vertical longitudinal'section through one form of construction of apparatus constructed according to my invention.

The jet-nozzle proper,a,of a jet-blowing apparatus is connected by the pipe b with a generator c, adapted to produce an infiammable gas-for instance, Dawson gas-which is generated by 'leading a mixture of steam and air to and into the burning coal contained in the lower part of the generator c. In the form of construction shown the burning coal is employed also for producing the steam necessary for generating theiniammable gas. The generator cis surrounded by a vessel d, forming the boiler, and the steam produced in this boiler' is led by a pipe e to an auxiliary j et-blowing apparatus j', driving air into a pipe g, so that a mixture of steam and air is produced in this pipe. The pipe g projects upward from a chamber r, connected with another chamber s by a number of pipes t. These pipes are heated by means of the hot gases issuing forth from the jet-blowing apparatus, as will more fully be described hereinafter, and the hot mixture of steam and air entering into and collecting within the chamber s passes over into a pipe g', from the end of which a part of said mixture passes through a branch pipe 71. into the generatorl c, in which said part of the mixture comes in contact with the burning coal, so that Dawson gas is prod uced.- This gas passes through the pipe b to the jet-nozzle proper a, and, also the other part of the mixture of steam and air flowing through the pipe g is driven to andinto the nozzle u through the pipe t', which connects said nozzle with the pipe g. The inflammable gas coming from the pipe b and the mixture of steam and air coming from the pipe o' get mixed within the nozzle a,and the iniammable mixture thus produced is ignitedby means of a piece of palladium-wire lo, located within the nozzle a. There arises thus a powerful fiame issuing forth frorn'the nozzle a into and through the air-nozzle Z, forming part of the jet blowing apparatus. The burning gas mixes with the air sucked in by the nozzle Z, and this mixture is then led through another nozzle m, forming also a part of the jet-blowing apparatus. The hot gases issuing forth from the whole jet-blowing apparatus pass into a channel o, which is crossed by the pipes t aforementioned, and these pipes are thus powerfully heated by said gases, so that also the mixture of steam and air flowing from the chamber r through the pipes t to the chamber s is very strongly heated, and owing tofall this the caloritc power of the inflammable gas is utilized in a very high degree. The products of combustion leave the channel 'v at w.

The air-nozzles Z vand m and the end part of the gas-nozzle k are inclosed in a casing fr, the upper part of which forms a turbine engine and contains, therefore, a turbine wheel y. The front wall of the casin g x is provided with guide-blades directing the air against and into the blades of the turbine, so that this Wheel is kept in rotation as long as air is sucked into the casing .fr by the action of the jet-blowing apparatus a l m.

The heat produced in this apparatus is IOO nearly completely prevented from iuj uriously affecting the turbine engine or the turbine wheel, respectively, as this is exposed only to the action of the cold air streaming into the casing from the outer atmosphere. I wish it to be understood, however, that Ido not limit myself to exactly this form ot' construction, as I may well drive the jet produced in the jet-blowing apparatus into a casing similar to the arrangement being then such that the turbine wheel is operated not by the outer air, but by the jet of combustion gases and air streaming forth from the jet-blowing apparatus.

Having thus fully described the nature of my invention, what I desire to secure by Letters Patent of the United States isl. The combination with the jet nozzle proper of a jet-blowing apparatus, of a generator adapted to produce an inflammable gas, a pipe connecting the gas-space of said generator with said nozzle so as to feed the latter with said gas and cause this latter to form the jet necessary for driving the jet-blowing apparatus, another pipe connecting the said nozzle with the outer air, a third pipe connecting said other pipe with the fuel-space of the said generator, and an auxiliaryjet-blower adapted to be actuated by steam and arranged so as to force air into the lastmentioned two pipes, as set forth.

2. The combination with the jetnozzle proper of a jet-blowing apparatus, of a generator adapted to produce an inammable gas or gas mixture, a pipe connecting the gasspace of said generator with said nozzle, another pipe connecting the said nozzle with the outer air,`a third pipe connecting said other pipe with the fuel-space of the said generator, a boiler so arranged as to be adapted to be heated by the burning fuel in said fuel-space, an auxiliary j et-blowerarranged so as to force air into the last-mentioned two pipes, and a connection between said auxiliary jet-blower and the steam-space of said boiler,as set forth.

3. The combination with the jetnozzle proper of a jet-blowing apparatus, of a generator adapted to produce an inflammable gas or gas mixture, a pipe connecting the gas, space of said generator with said nozzle, a boiler so arranged as to be adapted to be heated by the burning fuel in said fuel-space, a jacket around the said nozzle, an air-nozzle forming part of the jet-blowing apparatus, a jacket around said air-nozzle, and connections .between said jackets and the waterspace as well as the steam-space of the said boiler, as set forth.

4. The combination with the jet nozzle proper of a jet-blowing apparatus, of a generator adapted to produce an iniiamrnable gas, a pipe connecting the gas-space of said generator with said nozzle, another pipe connecting the said nozzle with a closed chamber, pipes connecting this chamber with another closed chamber, an auxiliary jet-blowing apparatus adapted to be actuated by steam and arranged so as to force air into the last-mentioned chamber, a boiler so arranged as to be adapted to be heated by the burning fuel in the generator, and a connection between the steam-space of this boiler and said auxiliary jet-blower, as set forth.

5. rPhe combination with the jet nozzle proper of a jet-blowing apparatus, of a generator adapted to produce an in flammable gas or gas mixture, a pipe connecting the gasspace of said generator with said nozzle, another pipe connecting the said nozzle with a closed chamber, pipes connecting this charnber with another closed chamber, an auxiliary jet-blowing apparatus adapted to be ac tuated by steam and arranged so as to force air into the last-named chamber, air-nozzles forming parts of the rst-mentioned jetblowing apparatus, a casing around the pipes which connect the two chambers, another casing surrounding the said nozzles, a connection between said two casings, a turbine wheel located in the second casing, and guide-blades fixed to said second casing and located opposite to the blades of the turbine wheel so as to actuate the latter by means of the air drawn into the said casing under the action of the first-mentioned jet-blowing apparatus, as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EDMUND KIKUT.
